Notes

This method reads and validates the document according to the Conformance property. Any conformance error or warning is reported in the Errors property or the Warnings property after the method finishes.

If the Doc property is null, the document is read into a new Doc object, which is returned; otherwise, the document is read into the value of the Doc property, which is returned.

Example

Here we validate a document against PDF/A-1b format.

string path = "../Rez/pdfa.pdf";
using (var op = new PdfValidationOperation()) {
  op.Conformance = PdfConformance.PdfA1b;
  using var doc = op.Read(path, null);

  if (op.Errors.Count > 0) {
    Console.WriteLine("Errors:");
    for (int i = 0; i < op.Errors.Count; ++i)
      Console.WriteLine(op.Errors[i]);
  }
  if (op.Warnings.Count > 0) {
    if (op.Errors.Count > 0)
      Console.WriteLine();
    Console.WriteLine("Warnings:");
    for (int i = 0; i < op.Warnings.Count; ++i)
      Console.WriteLine(op.Warnings[i]);
  }
}
